Hi,
I try to migrate my website from V7.15.7 to V8.1
I downloaded V8.1, unzipped, then copied the /bin and /Umbraco folders to my hosting using ftp
When I go to mywebsite/umbraco to start the wizard I got the following error:
Could not load file or assembly 'Microsoft.AspNet.SignalR.Core' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.IO.FileLoadException: Could not load file or assembly 'Microsoft.AspNet.SignalR.Core' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
So I also copied the web.config (and made sure to put my connection string , as well update:
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not load type 'Umbraco.Core.UmbracoApplicationBase' from assembly 'Umbraco.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null'.
Source Error:

What do I do wrong?
How can I migrate from V7 to V8?
I was followed the documentations but still getting the error.
The easiest solution is to create a new project based on v8 (latest) and change connnectionstring to the old v7 database. Do this locally and not online.
our approach for migrating is:
1. copy connection string from v7
2. create new project (visual studio) and install umbraco v8
3. set connection string to v7
4. migrate by running in IIS Express
Hi, thanks.
I tried to use VS, didn't really work. Also, how do you deploy after install locally? I didn't set a CI/CD process, and I'm not using gitlab or any runner. it's my personal website that I develop and run by myself. So I rather do it through the regular process with the ftp
Here's my question: I didn't understand - when migrating from 7.x to 8.x - can I just do the regular update of copy /bin and /umbraco or I must spin up a new fresh empty 8.x website, then recreate the views?? it's little confusing.
Is it an issue with .NET Framework version - I remember similar issue being reported when people first started using V8 a while back, aha, there is a forum post here

Then go further to v9, 10 or 11.

I, personally, spin up a brand new instance of v8 and then I copy over views, css, scripts etc to the new site. Which has worked many times for me.
However, I am having the same problem that you are having now - with the same error when I try to load up the site.
Could not load type 'Umbraco.Core.UmbracoApplicationBase' from assembly 'Umbraco.Core, Version=8.0.0.0, Culture=neutral, PublicKeyToken=null'.
Has anyone seen this or can help after a v 7.15.7 upgrade to 8.18.7 ?
I'm having the exact same error updating to 8.18.6. Did you manage to solve this?
Hi Angel
Is it an issue with .NET Framework version - I remember similar issue being reported when people first started using V8 a while back, aha, there is a forum post here

and

So this might be what is also troubling yourself ?
